Portal is one of the most interesting physics games available on the market and its developers have decided to distribute it for free until September 20. The game puts our imagination to the test because it is built from a series of puzzles that we have to solve and to do this we have to help ourselves with gravity and the "weapon" that we have at our disposal. Portal is a very good way to spend a few hours in front of the computer and the game is worth installing considering that it is free.
Portal ™ is a new single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay.
To install Portal you must have an account on the platform Steam and must download the game from here. Both the account and the game are free, so I can only wish you happy gaming.
